    Assessing reliability and validity of the Child PTSD Symptom Scale in portuguese adolescents
    (Edições Universitárias Lusófonas, 2019) Pinto, Ricardo José Martins; Santos, Patrícia Correia; Castro, Maria Vieira de; Jongenelen, Inês Martins; Levendosky, Alytia; Maia, Ângela Rosa da Costa; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
    Objective This study assessed psychometric properties of a self-reported measure of posttraumatic stress disorder (PTSD) for adolescents based on DSM-5 criteria–the Child PTSD Symptom Scale–Self Report. We tested the internal consistency, test-retest reliability, and convergent validity. Method The participants were 317 Portuguese adolescents (53% females) between 13 and 17 years old who had experienced at least one traumatic event or one childhood adversity. A subset of the sample (n = 85) completed test-retest measures (interval range between 5 and 7 months). Results Analyses revealed good to excellent internal consistencies, moderate to good agreement test-retest reliability, and good convergent validity. Conclusions Results supported the use of the CPSS-SR-5 scale as a valid and reliable measure for the identification of PTSD symptoms and probable diagnosis according to DSM-5 criteria in Portuguese adolescents.

    The impact of psychopathology associated with childhood trauma on quality of life in portuguese adolescents: a two-wave longitudinal study
    (Edições Universitárias Lusófonas, 2021) Pinto, Ricardo José Martins; Castro, Maria Vieira de; Silva, Laura; Jongenelen, Inês Martins; Maia, Ângela Rosa da Costa; Levendosky, Alytia; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
    Introduction: The aim of this study was to explore the mediating effect of psychopathology between childhood adversity and trauma and quality of life (QOL) in adolescents. The second aim of the study was testing the moderation by social support of this mediation effect. Methods: Self-reports of childhood adversity and trauma, QOL, social support, and psychopathology were collected from 150 Portuguese adolescents' who had been exposed to at least one traumatic event or one childhood adversity (Mage = 16.89, SD = 1.32). The surveys were administered at two time points with an approximate time interval of 1 year. Results: Indirect effects were observed for depression (B = −0.33, CI [−0.62, −0.11]), somatization (B = −0.52, CI [−0.82, −0.23]), and post-traumatic stress symptoms (PTSS) (B = −0.23, CI [−0.45, −0.01]), but not for anxiety (B = 0.20, CI [−0.08, 0.50]). A moderated mediation was found between social support and depression (B = −0.10, CI [−16, −0.04]), and PTSS (B = 0.03, CI [−0.1, −0.05]), but not for somatization (B = −0.02, CI [−0.8, 0.05]). Conclusions: We found that depression and somatization were strong mediators of the relationship between adversity/trauma and QOL, whereas PTSS was moderately mediated this relationship. Anxiety did not mediate this relationship. The moderated-mediation effect of social support was only found for depression and PTSS. The improvement of QOL in adolescents exposed to childhood adversity and trauma should include the assessment of psychopathology symptoms and social support, with the aim of identifying risk and protective factors.
